[Gift ①]
🎁All customers who purchase during the campaign period🎁

・1 peridot, oval cut, by Saint-Jays; 1 chic color spinel; 1 blue spinel; 1 step cut red spinel; 1 black tourmaline in quartz; 1 cobalt spinel rough stone
Tourmaline in quartz is a type of quartz with needle-shaped tourmaline inside.
The sharp patterns created by the black tourmaline are beautiful against the cool, clear color.

1 Paraiba tourmaline from Brazil, 1 celestite, 1 pink spinel (including silky pink), 1 platinum spinel (2mm) from Myanmar, 1 taaffeite or cobalt gahnite, 1 red spinel rough from Myanmar
Celestite is named after its beautiful color, meaning "stone of the sky."
What's fascinating is that the mysterious nuanced colors expressed in the stone are different from the blue sky.
We selected beautiful red spinel rough stones that show the beauty of their color and transparency even in their rough state.

Star spinel is a rare gemstone that has a clear star shape when exposed to light.
It reminds me of the first star shining in the night sky.
